FAUCET.

Specilication of Letters Patent No. 23,533, dated April 5, 1859.

To all whom it may concern:

Be it known that I, GEORGE W. RANDALL, of Boston, in the county of Suffolk and State of liiassachusetts, have invented a new and useful Faucet or Hydrant, which I term the Duplex Faucet, and I do hereby declare that the same is fully described and represented in the following specification and the accompanying` drawings, of which Figure l, denotes a front elevation of it. Fig. 2, a vertical section of it. Fig. 3, a horizontal section taken through the series of induction pipes. il, is a top view of it.

The nature of my invention consists of a eoml'Jination of two taps or valve tubes and a case or body provided. with two or more conduit pipes, the whole being arranged, constructed and applied together in such manner as to enable either of the currents of fluid conducted into the case by either of its conduits to be discharged out of the lower end of the inner tap or valve tube and the remainder of the currents to be shut off therefrom. Or my said invention may be used for the purpose of leading a current of a iuid into any one of a series of conduits at pleasure or as circinnstances may require.

in the drawings, A, represents the case or body part of the duplex faucet, while B, and C, are the valve tubes or taps. The outermost tap, B, not only receives the inner tap C, but is received by the case in like manner or as the tubular valve eduction pipe of a common faucet enters and works in the body or induction part of such a faucet. The case or body A, is provided with two or more radial conduits or pipes D, D, D, D, which open into the tap hole, E, E, thereof, as shown in F ig.

The tap, B, is tubular and ground to lit and turn in the hole E, F, with a water tight joint and it has an inlet hole n, made horizontally thrmlgh it and with its center in the plane of the axes of the conduits, as shown in Figs. 2, and 3. Furthermore, the tap B, may be furnished with a series of radial arms Z), Z), etc., extending from it as seen in the drawings such being for the purpose of enabling a person to revolve the tap within the case A, so as to bring the inlet hole of the tap in a line with any one of the conduits D, D, D.

The inner tap is open at bottom and closed at top. It extends through the outer tap and should be ground to fit it so as to turn on it with a water tight joint.

A hole or passageway c, should be made through the side of the inner tap C, in the same plane with the axes of the conduits as seen in Figs.

2, and 3.

The head or that part cl, of the tap C, which extends above the tap B, may be milled as shown at c, e, in Fig. l, or it may be provided with any other suitable means by which the tap may be easily turned around axially within the outer tap as that is capable of being turned within the case A.

A long notch j, made in the upper part of the tap B, (as shown in Fig. 1,) serves in connection with a pin g, extending from the inner tap C, to determine the extent of rotary movement of the inner tap, the inlet passage of the tap C, being brought into line with that of the tap B, when the stud is against one end of the notch. By moving the inner tap so as to carry the inlet orifice thereof beyond that of the outer tap, the lat* ter orifice will be closed. By means of the auxiliary or inner tap combined with the outer tap as described, a Huid may be drawn from either of the conduits and the change made from one to the other withoutI any draft from any of those which may be intermediate.

lVith but one tap and a case provided with a series of conduits, it will readily be seen that whenever it might be desirable to draw a liquid from a conduit, such conduit might be so situated that in order to bring itinto line with it, the inlet orifice of the tap, such orifice would have to pass across some one or more of the other conduits, in which case, some of the liquid from them would be likely to flow into it and run out of the discharge end of the tap. Now, the auxiliary tap enables us to sluit the inlet orifice of the outer tap and keep it shut while it may be in the process of being moved from one of the conduits to any other of the series. After the change may have been made the inner tap may be turned so as to carry its inlet orilice into line with that of the other tap, in which case, the liquid will flow directly int-0 the inner tap and be discharged from its lower end.

My invention is particularly calculated for drawing ale or spirits or liquors of vari` ous kinds from sundry reservoirs and through one discharge tube or tap.

In order that the Huid which may enter the inner tap may be discharged therefrom or not hindered by atmospheric pressure from free lowage from it I provide the inner tap with an air passage,p,to extend vertically upward from the lower end of the tap and alongside of the bore of the same and to open into the inlet orifice of the said tap. As air can flow through this passage upward into the bore of the inner tap, the pressure of the atmosphere cannot operate toward retaining any of the fluid in the tap. The arrangement of the said air passage is such that, should any liquid be discharged by it, it will pass downward with or close to the stream that may flow out of the tap. Vere the said air passage made through the top part of the tap it would operate to let air into the top, but at the same time, more or less liquid would be likely to be discharged from it, in a wrong or inconvenient direction. The peculiar arrangement of the air passage with respect to the bore of the tap or so as to open out of the lower end of the tap, or discharge liquid downward is an improvement and productive of a useful, result, as by means of it, the liquid that may be discharged from the tap and air passage may be received into the same vessel.

There may be an index on the outer surface of the outer tap. Also, a series of such marks or divisions on the outer surface oi' the ca se A, as will enable a person with such index to stop the inlet orificel of the tap against any one of the conduits of the case.

That I claim is#- Y 1. The combination of the auxiliary or inner tap with the outer tap and the conduit case, provided with two or more conduits, the whole being constructed and made to operate together substantially as specified.

2. I also claim the arrangement of the air passage, p, so as to discharge with reference to the discharging end of the inner tap substantially as described.

In testimony whereof, I have hereunto set my signature.
